Yes, have a couple of the Heltec boards with Lora 868/915 and one with just the Wifi Kit.

Espruino generally works very well. With connected sensors, power sensitivity seems pretty fussy at times so see more reboots than I was expecting but otherwise able to get OLED, Lora, WiFi client all working well.

Support for Wifi Base, Bluetooth and ESPNow are not yet functional as far as I can see.
